Why Saint Bernards need this much exercise

Saint Bernards were bred by monks at the Great St. Bernard Pass in the Alps to find and rescue travelers in snow.

Walking tips for Saint Bernards

Moderate, unhurried walks keep a Saint fit without stressing big joints.
Heat is a real risk. Walk only in cool weather and carry water.
Puppies grow fast, so keep their exercise gentle and short.
Protect growing joints: no forced running or repetitive jumping until growth plates close, around 18 to 24 months.

Saint Bernards in hot and cold weather

Heat: Saint Bernards don’t handle heat well. Their heavy coat traps heat. Walk at dawn or after sunset in summer, keep walks short once it feels like 75°F (24°C), and limit outings to potty breaks above about 82°F (28°C). Check today's heat risk.

Cold: Saint Bernards are built for cold weather and usually enjoy it. Paws still need protecting from salt and ice, and very young or old dogs feel the cold more. Check today's cold risk.

Saint Bernard exercise FAQ

How long should I walk my Saint Bernard?

A healthy adult Saint Bernard needs about 30–45 minutes of exercise a day, best split into 2 to 3 short walks. Walks, play, and training games all count toward the total.

How far can a Saint Bernard walk?

At a normal walking pace, that works out to roughly 0.5–1.5 miles (1–2.5 km) a day for a healthy adult. For Saint Bernards, time and sniffing matter more than distance, so keep the pace comfortable.

When can a Saint Bernard puppy go on long walks or runs?

Wait until growth plates close, around 18–24 months for a giant breed like the Saint Bernard. Until then, follow the 5-minutes-per-month rule: about 20 minutes per walk at 4 months, up to twice a day, plus free play.

Can Saint Bernards handle hot weather?

Not well. Their heavy coat traps heat. Walk at dawn or after sunset in summer, keep walks short once it feels like 75°F (24°C), and limit outings to potty breaks above about 82°F (28°C).

Do Saint Bernards need a coat in winter?

Rarely. Paws still need protecting from salt and ice, and very young or old dogs feel the cold more.
